SLUG-MOLD. i

Specification of Letters Patent.

Application led April 22, 1912. Serial No. 692,432.

To all whom it may concern Be it known that I,v JOHN KEENAN, a citizen of the United States, and a resident of -Chicago, county of Cook and State of Illifnois, have invented certain new and useful Improvements in Slug-Molds, of which the following is a speciiication.

My invention relates to improvements in line casting machines and has particular reference to improvements in slug molds for such machines.

The obj ect of myA invention is to provide a Amold for slug casting machines which shall facilitate and cheapen the production of skeleton slugs.

A further obj ect of my invention is to pro-A vide a .mold by means of which skeleton slugs of different lengths can. be produced without the necessity of using liners of spethe face ofthe slug.

"cial cross section.

vided in one face with a series of recesses, Y

openings or notches separated by partitions, and by .means of which the molten metal is Y fed from the body. of the mold to the wide face.

My invention consists further in a slug mold adapted to make skeleton slugs of difrferent specified lengths and having grooves' in oneface adapted to feed the metal to My'invention will be more readily understood by reference to the accompanying drawings forming a part of this specification, and in which- Figure l is afront elevation ofa mold of the type commonly employed in connection with linotype slug casting machines and made in accordance with my invention; Fig. 2 is a vertical section of the mold upon the line 2-2 of Fig.`1 shown din connection with a matrix in 'casting position in front of the mold; Fig. 3.is a perspective view of a skeleton' slug, such as would be produced in` or by the mold illustrated -in Fig. l; Figs. 4 and 5 are detail transverse sections of the slug upon the lines H and 5T5 .respectively of Fig. 3.

` linotype machines.

It .should be understood that skeleton slugs have been made heretofore on linotype machines, but. the use of the molds in making these slugs has necessitatedy theemployment of special liners, l`when it is desired to make .slugs of any length shorter than the whole length of the mold. These special liners have been required for thement necessary for producing these slugs requires.` the inyestment of a large amount of capital in special liners. Each linotype machine carries as its standardv equipment a complete set of liners which arevsubstan- Itially parallel in thickness and are used for making the standard solid lino-type slugs of the different lengths required and one of the particular objects of my invention is to provide a mold of such form that skeleton slugs can'be produced thereby of any desired length with the usevof the standard vparallel thickness liners which is the 'standard equipment ofall linotype machines.

vLintoype, as used herein, will be understood to refer to any of the slug casting machines and is not limited to the machines known as the linotype machines.

In said drawings A indicates a modified.

standard linotype mold similar to the standard mold which. is usually employed upon It consists of a base member 2 and a cap member 3, separated from each other by a space 4: andheld in position one upon the other by any suitable means such, for instance, as screws 5. The cap is held above the base by means of a 'permanent liner or spacer 6 at one end'and a changeable liner or spacer 7 at the other end. These spacers are clamped between the adjacent opposed faces of the base and cap and are held in position by the clamping of the cap upon the base andare adapted to space the two parts of the mold apart a sufi'cient distance to provide a space in v' .ich

in the body thereof. To adapt the mold to produce slugs which have iaees that are wider than the thickness otl the thin portion ofthe body I provide the cap. in its outer face, with a series of recesses or openings S separated from each other by a series ot thin partitions t). These recesses or openings open through the face l() ot the mold and through the bottom l1 ot the cap; that is. they form continuations ot' the slug space l and extend the front t'ace ot the mold space upward a suicient distance to cooperate. vwith the letter forming space 12 provided in the matrices 14. with which the mold is adapted to be employed to form a skeleton slug. A certain number ot' the spaces S extend through to the r ar face ot' the mold and thereby the/thin portion ot the body ot the slug is provided with ribs 15. which together with the thin portion ot the body ot' the slug 1G formed in the slug space Jr make the complete skeleton slug, as illustrated in Fig. 3. The recesses S and partitions 9 form what may properly be termed a longitudinal' groove along the front edge of the cap which is divided or closed at intervals by the partitions 9.

It is desirable in making slugs to be able to produce slugs ot' diti'erent lengths and to be able to vary these lengths within certain definite dimensions. To make a slug. in the mold which have provided. ot a length which is shorter than the complete length ot' the. mold. itis simply necessary to select the liner T of a suitable length so that its inner end will be properly spaced from the opposite permanent liner that a slug space ot' the required length is formed between the opposed 'ids ot the two liners. and T arrange thel partitions 9 in such relation to the lengths ot' slugs which it is desired that. the mold shall produce that the inner end 1T ot the adjacent liner T shall coincide with one ot the partitions` 9. Consequently, when the liner is in position between the base and cap and itsinner end licoincides with one ot the partitions t) the molten metal. of which the slug is l'oi'med, is etl'cctually prevented i'rom [lowing along the t'ace ot' the mold as'the liner and the partition 9 with which the end coincides l'orm a complete partition or dam at that end of the mold. 'l`he combined width of one ot the spaces P and the adjacent partition t) can be ni`a`dc in any desirable dimension. but l preferably make this dimension equalto a printei"s m" so that the re-` sultant variation in the length oll the slugs is`in 1n lengths. lt will be understood, ol'l course. il. it is desired to produce any other length ot" slug which might vary by hall m i or other dimensions it is only necessary. in nianut'actm-ing thc mold. to pla`ce one ot' the partitions in the desired position to coperate with the necessary length ot liner to produce the length of slug desired.

As many modifications of my inventiow will readily suggest themselves to those whogm are skilled in the art, I do notlcontine or limit my inventionl to the specific construe tions herein shown and described.
